To Activate Heat Pack
Squeeze the metal coin located inside the hot pack until you hear a CLICK!! The liquid will begin to crystallize and heat up. To speed up crystallization, simply shake the pack until it is completely crystallized. Massage the pack for a few seconds to make it soft and pliable. Apply to desired area of your body. Use until all the heat has been expended and the pack has gone cold. You will notice that the pack is very firm at this point and solidified with crystals. This is normal. Dont now store it in this crystallized state and it is not good for the product so now you are going to return it to its original liquid state so that you can use it again next time.
"Recharge" your Pack After use so it is Ready for Next use
Place the pack into a non-stick pot or rice cooker full of water and bring a boil. Let it boil for the designated number of minutes given to you in your instructions. The object is to return the crystallized solution back into its liquid state. If you do not have a non-stick pot then place a dish cloth on the bottom of the pot to prevent the pack from possibly sticking or burning (alternatively, you can wrap the hot pack in a cloth or towel).
Notice the Crystallized State of your Packs
Depending on the size of the pack or number of packs being boiled at the same time, it may take anywhere from 5 to 30 minutes to melt the crystals back to liquid form.
NOTE: If the crystals are not completely liquefied, they will re-crystallize and you will have to boil the whole pack again to be able to re use it. So it's best to just boil out all the crystals the first time. You can boil as many at a time as fit in your pot.

Boil until the Crystals Turn to a Clear Liquid Again
You will know when they are done for all the crystals will have been liquefied and the packs will become completely clear again. Remove the packs from the pot with soft-tipped tongs. Allow to cool to room temperature and click it again to activate its heat again anytime thereafter.
To Use Cold
Place the pack in the refrigerator while still in liquid form until cold. DO NOT PLACE IN THE FREEZER. Freezing may cause damage to the pack. If placed in the freezer, after a certain amount of time, the extreme cold will activate the hot pack and once removed from the freezer, while it may appear to be frozen, it in fact needs to be boiled to return to its liquid state (leaving it out will not "un-freeze" it as it never actually froze in the first place.)

Remember to keep the water at a continuous boil the entire time, even a low boil:
Neck/Shoulder : 20 minutes
Back/Abdomen: 15 minutes
Knee/Joint : 10 minutes
Hand Warmer : 5 minutes
